pyJsonEdit

Edit parts of inconsistently formatted json.

It's just a bit slower that doing this by hand!

matcher

Now you can easly select nodes in json tree

syntax:

selector	action	node type	comments
*	select all items in current node	-
[n]	select n-th item of curent node	array
{n}	select n-th item of curent node	object
key	select node chilld by name	object
"key"	select node chilld by name	object
>	mark current node as seleced	-
a=b	check if current node has child 'a' with value 'b'	object
:before	add text before selected node	-	must at end of pattern
:after	add text after selected node	-	must at end of pattern

example 1:

key > [0]

this pattern will match one element by:

1. selecting "key" element in root node (assuring that is an object)
2. select first element in it (assumintg its an array)

example 2:

name > *

this pattern will match multiple elements by:

1. selecting "name" element in root node (assuring that is an object)
2. select all element in it

def modify(node,ctx):
   return "'<"+str(1)+">'"

node - matched node

ctx - context in witch node was matched: file_name & match_nr

pyjsonedit-modify "*" /home/dave/somefile.py "{'a':1}"

example: mask multiple nodes

$ pyjsonedit-mask **"quiz > * > q1 >*"** DOC/example.json

{
    "quiz": {
        "sport": {
            "q1": {
                "question": XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,

            }
        },
        "maths": {
            "q1": {
                "question": XXXXXXXXXXX,
                "options": XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,
